I think Atelier 801, needs to stick with one game, and continue to upgrade it.
My favorite though, is Transformice, it's much more social, and a lot more simple.
I think they should work on making things cheaper. All the same, I think of Fortoresse, Bouboum, and Nekodancer as minigames.
I just personally think it would be smarter to stick to one game at a time.

I don't know if I put it in the right area.

If you wish to discuss this topic, you can do so in the Discussion subforum under the Atelier801 category, as this is not exactly Nekodancer related.
We currently cannot move topics from one category to another, so you may recreate the thread there. Just make sure you use a more suitable thread title and present it in a way that'd promote discussion rather than just 'share your opinion.

Thanks!
